Newton’s law of gravity is used with great success in most everyday situations, and indeed, in planning planetary space missions such as the Rosetta probe.

Question

However, Einstein’s theory of general relativity and a theory of quantum gravity are needed to describe the observed effects of gravitational interaction under different circumstances.
Write a short account, explaining the circumstances where general relativity and quantum gravity depart from Newton’s theory, giving one example of an effect or prediction for each of these alternative theories
